SIGNALING APPARATUS FOR RAILWAY-TRAINS.

SPECIFICATION forming part Of Letters Patent No. 668,588, dated February19, 1901. Application filed September 18, 1900. Serial No. 30,433. (Nomodel.)

To all whom it may concern:

Be it known that I, HENRY SMITH, a subject of the Queen of GreatBritain, residingatQet Somerleyton road, Brixton, London, England, haveinvented certain new and useful Improvements in Signaling Apparatus forRailway-Trains, of which the followingis a specification.

The object of this invention is the improved construction andarrangement of appliances or apparatus for indicating to the driver of alocomotive the gradients and the name of a station or block-box,together with the signals, whether distant, semaphore, or home, andwhether they are at danger or line clear, and also recording theposition of the various signals during the travel of the train orengine.

The invention will be clearly understood from the following description,aided by the accompanying drawings, in which Figure 1 is a frontelevation of the indicating and recording appliance, the front of thebox being removed. Fig. 2 is a side sectional elevation through the line1 1 of Fig. 1. Fig. 3 is a side sectional elevation through the line 2 2of Fig. 1. Fig. 4 is a side sectional elevation through the line 3 3 ofFig. 1. Fig. 5 is a side sectional elevation through the line 4 4 ofFig. 1. Fig. 6 is a side section of the danger or line-clear indicatingportion of the apparatus. Fig. 7 is a plan, and Fig. 8 a side elevation,of a rail-track, showing the approximate positions of the variousdevices for operating the appliances shown in the previous figures. Fig.9 is an elevation of. a locomotive-cabin and showing the approximateposition of the apparatus, the operating-rods being constructed foractuation during either direction of travel of the engine. Fig. 10 is anelevation of the casing containing the mechanism and operating-rods.

A is a box or casing affixable to the cabin of a locomotive or in theguards, brake, or other part of a train, as desired. This box A hassuitable bearings for carrying rollers B O D, the roller B beingprovided with a roll of paper, which paper E is passed under the rollerO to the roller 'D, to which it is secured. The paper is printedthroughout its length with the names of the stations, theindicationsthatis to say, distant, semaphore, or home -of the signals,and the various gradients, according to the route the train is to takefor the journey, the paper being removed by the superintendent or otheroifieial at the end of the journey and a fresh roll substituted to suitthe new route to be traversed by the train. The rollers G and D arebelted together, preferably by a band F, Fig. 1, so that they movetogether.

G H I are rods depending from the apparatus to within a short distanceof the ground for actuating, as hereinafter described.

The rod G (see Fig. 2) is in connection with a crank-lever J, whichcarries at its free end a springcontrolled pawl K, engaging theratchet-teeth L on the roller 0 for moving the same when the rod G isactuated, the roller 0 to shift the paper on the required distance toexhibit through the opening P a fresh indication,a spring M, arrangedbetween brackets, returning the rod G to its normal position.

N is a spring-controlled pawl engaging the ratchet-teeth L to prevent areturn move ment of the roller O.

The rod H (see Figs. 3, 4L, and 6) carries a plate or board Q, coloredgreen, and when the rod 11 is lifted the plate Q will be exhibited atthe opening R and locked in that position by reason of the latch-plate Sbeing drawn in under the board Q by the spring T, as shown at Fig. 6.

Pivoted to the front plate of the casing within the same is aspring-controlled rocking lever U, the upper part being provided with aninking or marking device and the lower with a roller, so that as the rodH is raised the roller will ride against the board Q until it comes toan angleedged opening, when the spring of the lever U will cause themarking end to press upon the paper and mark the same, say, with a greenspot, to record that the signal indicated line clear when the driverpassed that particular signal.

The rod I, Fig. 5, has a nose W at its uppermost end, which in itsnormal condition holds a rocking lever X (similar to that justdescribed) under the action of its spring and with the marking end awayfrom the paper; but when the rod 1 is lifted the nose W is removed fromcontact with the roller end of the rocking lever X for its spring toforce the marking end onto the paper to record that the driver hadpassed the signal when at danger by marking on the paper, say, a redspot, against the name of the particular signal printed thereon.

On each of the rods Q. HI is fitted a pin or projection Y, either ofthese when a rod is lifted actuating its respective lever -Z, this leverZ being fixed to an axle 17, carrying at the opposite side an arm orlever c, which is hinged to a rod (Z, for actuating a bell mechanism 6,so that each time either rod is lifted the bell f is struck to warn thedriver that the apparatus has been acted upon.

The latch-plate S is provided at the free end with an angled face g, sothat when the rod G is lifted to exhibit a fresh indication an angledrecess ZL in the rod will engage the angle-Face g of the plate and pushthe latchplate S away from contact with the plate Q and allow the plateQ. and rod H to be returned to their normal positions by the spring Z.

Between the metals and at the desired distances apart I fit thenecessary appliances for actuating the mechanism heretofore describedduring the travel of the train and preferably before each signal. Theseappliances consist of a camber j, which is fixed to the sleepers andemployed for actuating the rod G, a hinged camber Z; for actuating therod I, and another pivoted camber Z for actuating the rod H, the cambersZ being connected together by a connecting-rod m. for actuating from thesignal-cabin through the wire 12 and lever 2), the wire a being the samewhich operates the signal, so that the signalman when he moves hissignal also moves the camber-s Z; Z by the same operation.

G, H, and l are short rods connected by shafts t to the rods G H I,respectively, through the links r, which are pivoted to the short rodsG, H, and I and the shafts g. This arrangement renders it possible foroperating the mechanism when the engine is traveling tender first.

S is a plate or board colored red, which is fixed in the casing in frontof the opening R to exhibit the danger signal when the plate Q is notoperated to indicate line clear.

Now supposing that a fresh roll of paper is placed in the casing and thetrain about to start upon its journey, and for the purpose ofillustrating the action of the apparatus 1 will describe the same asccurring between two stationssay Moorgate street and Aldersgate-and itis assumed that there are three signals between each station-t. 6.,distant, semaphore, and home signals. At the opening P will be exhibitedMoorgate, and on the Signalman operatii'ig the home or starting signalto indicate line clear the camber Z will be lifted and operate the rod[I to indicate to the driver that the line is clear on which he startsthe train, and at some distance away G will be actuated by the fixedcamberj for revolving the roller'G to move the paper to exhibitAldersgate, distant, the rod G returning to its normal position by itsspring M. Now assuming the Aldersgate, distant signal has been operatedto line clear, the signalman will have on the pulling of his lever foractuating the signal operated the cambers 7c Z to lower the camber laand place Z in the path of the rod H so that when the train reaches thecamber the rod II will be operated and the board Q or line'clear signalexhibited at the opening R to indicate to the driver that the line isclear to the next signal, a mark also being made by the inhei-U atft-heside of the printing Aldersgate, distant to record that the line wasclear, the board Q. being retained in the exhibit position by thelatchplate S, ashetore explained. The train passes the distant signaland goes on until it reaches the next camber-j, which actuates the rodGto indicate to the driver in the manner already explained that he isapproaching another signal, the indication this time being Aldersgate,semaphore. lhisactuation of the rod G causes the latclrplate S to beacted upon to release the board Q and rod l-Lwhich return to theirnormal condition ready for a fresh operation, the danger-boa rd S nowbeing exhibited at the opening R. The train passes along until itreaches the camber 7t, which, it the line is clear, has been lowered, sothat the train can pass on until the camber Z is reached, and thishaving been raised, as with the dist-ant signal, actuates the rod H toindicate line clear for the train to continue its journey until thesemaphore signal has been passed and the next camber-j reached foroperating he roller 0 to indicate Aldersgate, home and release thelineclear signal Qand rod H, and, assuming the train is to stop atAldersgatc, the home signal will be at danger, and in consequence ofthis signal not having been operated the camber 7; will have been raisedto be in the path of the rod Hand the camber Z lowered, the

camber 7t acting upon the rod I to mark the paper that the line wasblocked, the danger-indicator S still being exhibed, so that the driverwill at once pull up into the station for the rod H to be again actedupon by the camber Z when the signalman operates the home or startingsignal to line clear to indicate to the driver that he can start, theapparatus being acted upon in the same way during the next section, andso on.

Should the driver after having passed the camber 7; when raised not pullup at the camber Z, the same will be known bythe fact that only thelever X will marl; the paper, whereas it he pull up at the camber Z theoperation of the signal for restarting the train will raise the camber Zto operate the rod H, this by the IIO lever U marking the paper at theside of the previous mark,this stamping not being viewed by the driver.

As will be understood, the arrangement of the cambers may be varied tosuit the particular features of the road, and in some cases the camber70 may be of undulating or wavy form to ring the bell the requisitenumber of times to indicate to the driver by the number of beats thenumber of whistles for the signal he requires, this being speciallyapplicable for junctions. Thus by this invention the driver of alocomotive-engine or a guard, or both, can, whether in fine or foggyweather or dark nights, ascertain during the travel of the train thename of the station, block-box, or set of signals he is passing and alsothe gradient of the road and whether such signal is at danger or lineclear, the position of the signals being also recorded upon the paperset that the superintendent or other oflicial on removing the roll ofpaper at the end of the journey can ascertain whether the driver passedany signal when at danger.
